Letters Patent No. 107,341,1latef1 September 13, 1870.

IMPROV'EMENT IN WATEwR-REGULATOR.

The Schedule referred to in these Letters-Patent and making part of the same.

To all whom it may con-cern:

Be it known that we, GEORGE W. Danni.' and AMOS S. MOON, of Blanchester, in the county ot' Clinton and State of Ohio, have invented a new and valuable Improvement in Boiler-Regulators; and we do hereby declare that the following is a'full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a side view of our invention. n

` Figure 2 is a partial vertical section, showing the interior of the boiler.

Our invention relates to means for preventing steamboiler explosions, and consists in a novel arrangement ot' the pump with the steam-boiler, together with novel means for opening the valve of an alarm-whistle.

A of the drawing represents a steam-boiler;

B, the suction-pipe; and.

O, the delivering-pipe of our pump.

D represents the pump proper, which is-rmly attached to the side of the boiler.

The pipe C passesl inside the boiler, deliveringr the water therein, which the pipe B receives from the tank. 'f

iVe place a small valve in the lower arm of the pump, at a, to which we attach -the crank e, and to the handle of said crank we aix thepit man n, in the manner shown.

The letter o represents the piston of the pump, to the head of which the motive-power is applied.

XVe 'ax a square block in the side of the boiler, packing the same securely, and make a cylindrical opening therein, adapted to receive the shaft, next mentioned.

The letterE represents a shaft passing through and rotating in the opening above described.

'lo the outer end of this shaft we attach the crank y, which is united at its lower end with the pitman n, as shown. Y

' The letter G'represcnts a float attached to the inner end of shaft E, and arranged to operate therewith, in the manner represented.

Oli the top Ofshaft E is a pin, u, Iirmly attached,

and arranged foi-actuating the bent lever m of the steam-whistle. y

H represents oin steam-whistle.connected with the side of the boiler. In the lower end of'this Whistle is a valve, to which the upper end of the lever m is united. When this valve is opened, the steam from the boiler rushes throgh it and' blows the whistle.

.Onr device operates as follows:

W'hen the oat G israised by the water in the boiler vbeyond the pointdesired for the water-line, the pitman n, operating on the crank e, closesthe supply- -pipe, and no more water is admitted; and again, when the oat falls below the desired water-line, the

pin u, operating in conj auction with the bent lever m, opens the valve in thesteam-whistle, andthereby gives alarm. l

XVe are aware that'a patent for an indicator has been granted to'Wm. McCormick, dated December 17 1867, which invention we hereby disclaim; butA nesses. i
